SPECIFIGATION forming part of Letters Patent No. 290,226, dated December 18, 1883,

Application filed May 18, 1883.

To all whom it may concern: 1

Be it known that I, MURRAY GIBsoN, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Composition for the Ornamentation of Walls and Ceilings, of which the following is a specification.

The object of my invention is the production of an improved plastic compound which shall be adapted to be applied to a Wall, ceiling, or other surface to be decorated, whether such surface be composed of brick, stone, concrete, wood, or other material, either in its natural state, coated with plaster, or faced with canvas or other textile or fibrous fabric, and which, when applied, shall be adherent thereto, and be also adapted to set into a rigid mass.

This compound is especially designed to be employed in the practice of a method of ornamenting walls and ceilings invented by me, application for patent for which was executed by me under the same date as the date of execution of this application.

This compound is especially designed for the ornamentation of interiors, as opposed to the ornamentation of exteriors, of dwellings or other buildings; and it is especially designed to be applied to surfaces which have been coated with plaster, although it is applicable, as already stated, to surfaces not solprepared.

The compound is composed of plaster-ofparis, sawdust, glue-Water or dissolved glue, and beeswax. The dry plaster and sawdust are mixed together and are thinned with gluewater which is added to the mixture and thoroughly commingled therewith until the mass (S pecimeus.)

assumes a pasty consistency. Liquid wax is to thin the compound ,in a manner likewise dependent upon the judgment of the workman, Then it is desired to cause the mass to set very rapidly upon the surface to which it is ultimately applied, the gluewater should contain less glue or be more dilute, and When it is desired that the setting should be more slow th glue-water is to contain more glue.

,ness to be applied to the surface which is to be ornamented with it according to my method already referred to.

claim .A compound for the ornamentation of walls, ceilings, and other surfaces, composed of plasterof-paris, sawdust, glue-water, and beeswax, substantially as described.

In testimony whereof I have hereunto signed my name this 4th day of April, A. D. 1883.
